After seeing Lisa Murphy do THIS I had to try it. All you need is a bottle of shaving cream and a box of corn starch. This was enough for two tubs of this wonderful, fluffy stuff! We poured about half the box of corn starch in each tub and then just squirted the shaving cream into them. We used the entire bottle between the two tubs. The incredible thing about this is that after a bit, it's moldable! The kids LOVED it. Now to replenish my shaving cream supply. Next time we will try adding some color too. So fun and a great fine motor and sensory experience!
